the amount of insulation to be removed.
3) Connect the wiring from the fire alarm control panels
Initiating Device Circuit (IDC), or any previous device on
the IDC to terminals 1 and 2 located on the pull stations
terminal strip. Connect the ne t device on the IDC or End-
of-Line Resistor (ELR) to terminals 1 and 2. Note: Maintain
consistent polarity with all connections throughout the IDC.
4) Connect the wiring for the normally open (N/O) au iliary
switch circuit to terminals 3 & 4.
